- AppIicatiori filed October 21, 1919. Serial No. 332,335.

T 0 all whom it may concern Be it known that JOHN CoNLoN, a citizen ofthe United States, residing at Plattsburg,

in the county of Clinton and State of New Cooling Systems, of which thefollowing is a specification.

This invention relates to an improvement in radiators for automobilecooling systems, and is particularly directed to a radiator designed forsimplicity in making repairs.

The improved radiator consists of the usual upper and lower reservoirsconnected by tube-structure, the tubes in my construction beingremovably connected to or secured in the bottom plate of the upperreservoir, and also removably seated in the upper plate The connectionsis concerned are readily accessible from the upper reservoir, and suchreservoir is provided with a removable cover-plate, through which thetube connecting means may be reached. This. permits the ready removal ofany tube or tubes, without disturbing any other portion or the radiator,and particularly without removing the radiator as a Furthermore, the useof the usual header plates to support the tube structure is dispensedwith, without many way detracting from the strength or stabilityof'thcradiator, the appropriate walls of the reservoirs serving as headerplates.

lnthe drawings Figure 1 is a perspective view of the improved radiatonFig. 2 is a vertical section of the same. Fig. 3 is a plan of theradiator, with the upper cover plate removed, illustrating theaccessibility of the 'tube'securing means.

The improved radiator comprises .an upper reservoir 1, and a lowerreservoir 2. These reservoirs which aside from the details hereinafternoted may be of any form or material, have edge flanges 3, and radiatorside plates 4, arranged to space the radiatorreservoirs the properdistance apart, are positioned between the side flanges 3. The platesthave flanges 5 to cooperate with the flanges 3, and bolts 6 areprovided to engage the appropriate flanges to secure the reservoirs andside plates into a rigid frame, capable however of ready disassemblingthrough removal of the bolts.

The upper reservoir 1 is fully open at top,

and is provided with a cover-plate 7, having the usual filling opening8. The cover plate s removably secured to the reservoir proper 111 awater-tight manner, as by bolts 9. The

lower reservoir 2 is open at its frontand. is

provided with a closing plate 10 for such open portion, with suchclosingplate res movably secured in place in a watertight manner, as by bolts11.

The reservoirs are united by the usual tube structure, and in devices ofthis character it has been heretofore proposed to con- StI11Cl3 tl11Stube structure as an independent unit, involving header plates in whichthe and securing the tubes in the upper reser-,

voir wall only, though seatingthe tubes'in a non leaklng manner 1n thelower reservoir.

tubes are secured, and such header plates This dispenses entirely withthe usual tube headers, and utilizes the reservoirs proper as suchtube-plates or headers. I

The tubes 12, of which of course there may be any desired number, engageopenings 18 in the bottom wall of the upper reservoir, and openings 14inthe upper wall of the lower. reservoir. The openings 13 in their lowerportions more or less snugly receive the tube, as at 15, beingthereabove enlarged at 16, with the wall of such enlarged portionthreadechas at 17. The openings 14 of the lower reservoir are formed tomore or less snugly receive the tube throughout the upperportion of saidopening, being then reduced somewhat in diameter, as at 18. The tube 12is applied from above, the cover-plate 7 having been removed. The tubeis provided at its lower end with athimble 19, forced or otherwisesecured therein to project below the lower end of the tube proper. Thisthimble fits the reduced portion 18 of the tube opening 14: of the lowerreservoir, and theshoulder formed by the different diameters of suchopening 1 1-, serves to support packing 20, which is thus pressed uponby the lower edge of the tube.

The thimble 19 prevents the possibility of this packing expanding intothe tube opening to interfere with the circulation.

The upper end of the tube extends through the openings 13, and packing21 is applied about the tube and pressed onto the shoulder formed by thedifferent diameters of the opening, by a gland nut 22, engaging thethreaded wall 17 of the enlarged portion of the opening 13. The glandnut is cored at 23 to receive the tube, and has a reduced opening abovethe tube, as at 2 L. This provides a shoulder 25 to bear on the upperend of the tube, so that as the gland nut is screwed into position, thetube will be correspondingly moved on the lower packing. The gland mayhave means, such as a kerf 26, by which it may be readily manipulated bya suitable tool.

It will be particularly noted that the tubes are held solely in place bythe gland nuts, and that these are readily accessible through the upperreservoir on removal of the cover plate. Therefore, any particular tubemay be tightened in place, by suitably operating the gland nut thereof,or any tube may be removed for replacement in an equally ready manner.The tubes lead directly to the reservoirs without interveningconnections, and hence the tubes are each separately secured in place,and not applied as an entire unit, as in the usual radiators.

If desired, and as preferred, a tube supporting plate 27 is arrangedtransversely of the radiator, being bolted to the side plates 4, andformed with tube receiving openings 2S, preferably punched therein toleave a burr 29 to further support the tubes.

The closing plate 10 of the lower reservoir permits ready inspection orcleaning of the lower reservoir, and also a complete drainage of theradiator when desired, asin freezing weather.

7 Having thus described the invention, what is claimed as new, is

1. A radiator having upper and lower reservoirs, tubes slidably engagingthe walls of both reservoirs, and a single means for engaging the wallsof one reservoir for securing the tubes in place and compressing thepacking between the tubes in both reservoirs in the same direction ofmovement as the movement of the single means.

2. In a radiator, an upper reservoir, a lower reservoir, tubes slidablycooperating with openings in the walls of such reservoirs, a singlemeans cooperating with the wall of one reservoir and operating in thesame direction of movement as the movement of the single means to sealthe connection of the tubes with both reservoirs, the upper reservoirhaving an opening through which said means is accessible, and a coverplate for such opening.

3. In a radiator, upper and lower reservoirs, tubes removably seated inopenings in the upper wall of the lower reservoir, packing underlyingthe ends of the tubes in such openings, the lower wall of the upperreservoir being formed with openings to permit the passage of the tubestherethrough, and a single means to engage the walls of the tubeopenings of the upper reservoir to exert an endwise pressure on thetubes.

l. A radiator having upper and lower reservoirs, the walls of therespective reservoirs being formed with tube receiving openings, meansarranged in the openings in the wall of the lower reservoir to providepacking spaces between said means and said wall, packing in said spaces,tubes slidably engaging the walls of the openings of the upper reservoirwall and bearing on the packing in the openings of the lower reservoirwall, and means cooperating with the wall of the upper reservoir toexert an endwise pressure on said tube.

5. A radiator having upper and lower reservoirs with the walls thereofformed with alined tube openings, a packing arranged in each of saidopenings, thimble fitting within the packing in each opening of thelower wall, and means having threaded engagement with the openings ofthe upper walls to bear upon the packing in said openings, and tooverlie and bear upon the upper ends of the tubes in said openings,whereby the op eration of said means will spread the packing in theopenings in the upper walls and force the lower ends of the tubes intoengagement with the packing in the openings or the lower walls.

6. A radiator having'upper and lower reservoirs with the walls thereofformed with alined openings, tubes arranged in said alined openings,packing surrounding the tubes in the upper wall openings, packingunderlying the ends of the tubes in the lower wall openings, and asingle element cooperating with the wall of each opening of the upperreservoir to exert an endwise pressure on the tube to compress thepacking at the lower end of the tube.

7. A radiator having upper and lower reservoirs with the walls thereofformed with alined openings, tubes arranged in said alined openings,packing surrounding the tubes in the upper wall openings, packingunderlying the ends of the tubes in the lower wall openings, and asingle element cooperating with the wall of each opening of the upperreservoir to exert an endwise pressure on the tube to compress thepacking at the lowerend of the tube, said element engaging the bearingupon the packing simultaneously with the movement of the tube.

In testimony whereof I aflix my signature.
